EVALUATION OF ENGINEERING PROPERTIES OF ASPHALT CONCRETE CONTAINING RICE HUSK ASH AS FOR BINDER COURSE FILLER
Abstract
The study investigate the evaluation of engineering properties of asphalt concrete containing rice husk ash as for binder course filler. Rice husks ash is a highly pozzolanic material, contains silica and surface specific area. That’s why many of the field in civil engineering it’s being used in soil engineering and in highway construction in flexible pavements as mineral filler. Therefore, there is a need to explore the use of various types of waste materials like Rise Husk Ash , stone dust, brick dust etc. In this study we use Rise Husk Ash as binders for course filler due to its various properties i.e. specific gravity, high silica content. In conclusion, this study showed that Asphalt that are important in construction of roads with very qualified pavements, improved longevity and pavement performance. By using rice husk ash as mineral filler in place of conventional filler increased the stability of roads thus the road can be withstand heavy traffic load and shows better service life.
